On the Asymptotic Order of Circuit Codes

Kevin M. Byrnes, Florin Spinu

In this note we prove that the maximum length of a $d$ -dimensional circuit code of spread $k$ equals $2^{d + O_{k} (l o g^{2} d)}$ , with the implied constant depending only on $k$ .

Sharp estimates for the convergence rate of Orthomin(k) for a class of linear systems

Andrei Draganescu, Florin Spinu

In this work we show that the convergence rate of Orthomin( $k$ ) applied to systems of the form $(I + ρ U) x = b$ , where $U$ is a unitary operator and $0 < ρ < 1$ , is less than or equal to…

Artin formalism for Selberg zeta functions of co-finite Kleinian groups

Eliot Brenner, Florin Spinu

Let $Γ\ H^{3}$ be a finite-volume quotient of the upper-half space, where $Γ \subset SL (2, C)$ is a discrete subgroup. To a finite dimensional unitary rep…
